Specification of Letters Patent.

Patented Sept.. ill, MMP?.

Application led November 15, 1915. Serial No. 61,715.

To all whom it may concern Be it known that I, PIERRE PLANTINGA, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Retorts, of which the following is a specilication, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to coal stops for inembodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.-

In said annexed drawing Figure l represents a front elevation of a Vfragmentary portion of a retort embodying my invention, with the door removed.

Fig. 2 represents an axial vertical section of such fragmentary portion of a retort.

Fig. 3 represents a front elevation of a fragmentary portion of a retort embodying a modified form of my invention.

Fig. 4 represents a vertical axial section of a Jfragmentary portion of a retort embodying such modified form of my invention.

My invention as illustrated in Figs. l and 2, contemplates its application to an inclined retort of a common construction in which the interior retort space is of the well-known and largely used cross-section. l"This welllmown cross-section is one in which the base of the cross-section is straight, the arch comparatively flat and the transverse dimension large as compared with the height. This type of retort, as used prior to my invention, contained this cross-section throughout its entire length and extended down to the outer extremity, as indicated by the dotted lines a in Fig. 2. l

In applying my invention to this type of retort, I cut away a portion of the upper Vand outer end of the masonry as at b so as to in any approved manner to the outer vertical surface of the masonry and adjacent to the discharge opening of the retort space, and this mouthpiece is provided with an ordinary door 2. From the upper interior portion of the body of the mouth-piece and depending therefrom, are two integral lugs 3, 3, having an open bearing fl. In this bearing is seated a horizontal pivotal rod 5 which is lixedly secured to a frame consisting of two angle bars 6, 6. These angle bars extend inwardly and downwardly from the pivotal axis and secured to their inner faces is the plate 7 intersecting the interiorretort space and intercepting the coal 8, holding same in the retort as required. As shown in the drawings, the dimensions of this plate 7 are such that it will, when in its normal or stopping position, have its lower end slightly removed from the bottom or vfloor of the retort.

Suitably pivoted to the lower end of the frame is a brace 9 whose outer end is bent downwardly and provided with a nose 10 adapted to engage a notch 11 formed in the lower interior portion of the mouth-piece, as shown in Fig. 2. This brace is provided with a hole l2 into which the operator may insert a hook (not shown) secured to a cable or chain passing over a trolley wheel suitably supported, by means of which he may lift the brace 9, disengage same from the notch 11 and thus permit the coal stop to swing outwardly and permit the coke from the interior of the retort to be discharged as required, while he is standing at a safe distance and even to one side ofthe front of the retort. The lower end of the plate being out of contact with the floor of the retort, it will be seen that the swinging of the stop is not resisted or impeded and its facility of operation is hence enhanced.

`Where the retort to which my device is applied is of that type in which the crosssection of the retort space is such as `illustrated in Figs. 3 and 4, in which the vertical dimension is considerably greater than the same dimension in the type of retort shown in Figs. l and 2, the cutting away of the upper and outer portion of the masonry is unnecessary, inasmuch as such increased vertical dimension permits my improved type of device to be applied, as will be readily understood by those skilled inthe art.

It will be observed thatby hanging or pivoting the coal stop in the manner described, that is, at a point or in such a manner that it may beswung Voutwardly and at the same time away from the bottom 5 or floor of the oven, such bottom or iioor is left clear and unobstructed and thus per- 'inits the coke to be most advantageously and readily discharged. Furthermore, by pivoting or hanging the stop to a lixed or stationary part 'of the retort, the `cover or door 2 may be removed or opened without disturbing -the stop. This is an obvious advantage in that the door may be completely opened before the coke is permitted to discharge, thus allowing the discharge opening covered by the door to be made absolutely free from obstruction before any of the coke ispermitted to pass therethrough.

In this manner it will be observed that I obtain an '-eiiicie'nt and economical form of coal-stop which may be readily applied to any type'of inclined retortat present in use.

It will be 'obvious to Vthose skilled in 4the art that the above-described -typeo'f coal stop inay be advantageously -appliedfto'an inclined or horizontal coke oven. In the event Ithat it is applied to a horizontal oven, 'howeveig it would be necessary to discharge "the coke by means other than the force or gravity, but the same advantages inhere, in so lfar as concerns making 'the stop independent -of the door 'or cover and also in 1so 'far as they relate to keeping the ioor or bottom'free from obstruction.

I-Iaving fully described my invention, what I claim and desire to secure by Letters Patent is l. The combination with a` retort including va mouth-piece; of a coal-stop mounted upon a stationary portion of the retort and adapted to swing outwardly and away from fthe floor thereof, whereby the coke may be discharged from beneath said stop. 4
